Electric hair edger and drive mechanism therefor



May 1 1964 J. T. KIRKLAND 3 ELECTRIC HAIR EDGER AND DRIVE MECHANISM THEREFOR Filed June 29, 1962 TlE'nl- 1 Q :2 no '8 a F D l2 A E TIE: IEL- INVENTOR. JOSEPH T-KIRKLAND ATTORNEY United States Patent 3,132,424 ELECTRIC HAIR EDGER AND DRIVE MECHANISM THEREFDR Joseph T. Kirkland, 145 Kingston St., San Mateo, Calif. Filed June 29, 1962, Ser. No. 206,401 3 Claims. (Cl. 30-210) An object of this invention is to provide an electric hair edger and drive mechanism therefor in which a reciprocating cutter is supported for rectilinear movement, this cutter having a straight row of cutting teeth lower edge that coact with a similar row of cutting teeth on a fixed cutter for edging hair along a substantially straight line. Moreover, the edger has a swingably mounted oscillating cutter having an arcuate row of cutting teeth along its upper edge arranged to coact with a similar row of cutting teeth on the fixed cutter so as to edge hair along a curved line, such as above a customers ears. Thus the edger may be used to edge hair along straight or curved lines by merely reversing the edger.

Another object is to provide a hair edger of the type described in which a single vibrator of an electric motor is made to operate both the reciprocating cutter and the oscillating cutter, whereby both may be actuated simultaneously. Thus the barber may reverse the edger at will during the edging of the hair and may readily edge the hair along a desired line.

Other objects and advantages will appear as the specification proceeds. The novel features of the invention will be pointed out in the appended claims.

Drawing For a better understanding of the invention, reference should be had to the accompanying drawing, forming part of this specification, in which:

FIGURE 1 is a top plan view and drive mechanism therefor;

FIGURE 2 is a side elevational view thereof, with parts being shown in section;

FIGURE 3 is a transverse sectional view taken along the plane 33 of FIGURE 2;

FIGURES 4, 5 and 6 are face views of the fixed cutter, the oscillating cutter and the reciprocating cutter, respectively.

While I have shown only. the preferred embodiment of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claims without departing from the spirit thereof.

of my electric hair edger Detailed Description In carrying out my invention, I provide a casing A having an electric motor B housed therein, the motor being provided with a vibrator C actuated thereby. The power for the motor may be supplied by a flexible cord 10 inthe conventional manner. c

It will be noted from FIGURES l and 2 that the casing A tapers towards it forward end 11 and the latter has a fixed cutter D secured thereto by screws 12 that pass through openings 13formed in the fixed cutter (seeFIG- URE 4) and these screws are threaded into the forward end of the casing. The fixed cutter D is formed with a straight row of cutting teeth 14 alongits lower edge, and an arcuate row of cutting teeth 15 along its upper edge, as illustrated in FIGURES 2, 3 and 4.

Moreover, a reciprocating cutter E is supported against the fixed cutter D for backand forth rectilinear movement. For this purpose, the screws 12 pass through elongated slots 16 that are fashioned in the reciprocating cutter (see FIGURES 3 and 6); 'The cutter E has a straight row of teeth 17 along its lower edge which register with the cutting teeth 14 of the fixed cutter D for edging hair along a substantially straight line.

along its An oscillating cutter F is swingably secured by a screw 18 to the forward end of the casing A for oscillatory movement about this screw (see FIGURES 1 and 3), and is supported against the fixed cutter D. The oscillating cutter F has an arcuate row of teeth 19 registering with the arcuate row of cutting teeth 15 of the fixed cutter D so as to edge hair along a curved line, such as above a customers ears.

The vibrator C is swingably secured by a screw 20 to the forward part of the casing A in the usual manner, and it has a lower arm 21 fitting into a recess 22 fashioned in the reciprocating cutter E for operating the latter (see FIGURES 2, 3'and 6). Also, the vibrator C has an upper arm 23 fitting into an opening 24 of the oscillating cutter F for operating the latter.

As clearly disclosed in FIGURES 1 and 2, all three of the cutters (D, E and F) are disposed in planes extending substantially at right casing A.

Referring to FIGURES 3 and 6, it will be seen that the reciprocating cutter E is provided with bevelled upper edges 25 that diverge upwardly relative to one another from the recess 22 in this cutter. The oscillating cutter F is provided with a lug 26 at its bottom that projects into the recess 22 of thereciprocating cutter E, with the pivot screw18 extending through this lug.

The oscillating cutter F has bevelled lower edges 27 that converge downwardly relative to one another toward the pivot screw 18, and these bevelled lower edges are spaced from the upper bevelled edges 25 of the reciprocating cutter E with sufiicient clearance so that both the oscillating cutter F and the reciprocating cutter E may be actuated simultaneously.

In use of my electric hair edger, a barber may utilize the teeth 17 of the reciprocating cutter E and the teeth 14 0f the fixed cutter D for edging hair along a substantially straight line. Moreover, the barber may be use the teeth 19 of the oscillating cutter F and the teeth 15 of the fixed cutter D for edging hair. along a curved line. Inasmuch as both the cutters E and F may be operated simultaneously by the same vibrator C, the barber may edge hair along straight andvcurved lines by merely turning the casing so that the desired cutters will be presented for use, and this may be done without stopping to close or open switches to make the change, once the motor B is placed in operation.

I claim:

1. In an electric hair edger and drive mechanism therefor:

(a) a reciprocating cutter supported for back and forth rectilinear movement, and having a straight row of cutting teeth;

(b) the reciprocating cutter being fashioned with a recess extending downwardly thereinto from its upper edge, and further being provided with bevelled-upper edges disposed on opposite sides of the recess and these bevelled edges diverging upwardly relative to one another;

(c) an oscillating cutter arranged in the plane of the reciprocating cutter and being swingably supported for oscillatory movements, and having an arcuate row of cutting teeth; a I

(d) the oscillating cutter being provided with a lug at its bottom that projects into the recess of the reciprocating cutter in spaced relation with walls of the recess, and havinga pivot for the oscillating cutter extending through this lug; I

(e) the oscillating cutter having bevelled lower edges disposed on opposite sides of the lug and these bevelled edges converging downwardly toward the pivot in spaced relation with the adjacent upper bevelled edges of the reciprocating cutter with sulfiangles relative to the length of 3 cient clearance so that both cutters may be actuated simultaneously, without one cutter interfering with the movement of the other.

2. In an electric hair edger and drive mechanism therefor for actuating a reciprocating cutter which is supported for back and forth rectilinear movements over a straight row of cutting teeth provided on a fixed cutter, and simultaneously swinging an oscillating cutter about a pivot and over an arcuate row of cutting teeth fashioned on the fixed cutter: t

(a) a casing having an electric motor housed therein,

the casing providing a support for all three cutters;

(b) a vibrator actuated by the electric motor for back and forth vibratory movements;

5 for, as set (0) the vibrator having one arm fitting into a recess 15 fashioned in the reciprocating cutter for operating the latter;

(d) and the vibrator having a second arm fitting into an opening fashioned in the oscillating cutter for forth in claim 2;

(e) and in which the vibrator and its arms define a substantially h-shaped member that is swingable about a pivot disposed intermediate the motor and the arms of the vibrator.
